eg. amethyst is said to be healing. Is this because a collective intention has gathered over centuries and opened a larger pathway to program amethyst in this manner, or is it due to the intrinsic nature of amethyst in the first place? Thank you for your thoughts.

the prime factor for amethyst is how did saturn imprint his code (on the given person who is wear it) AT THE TIME OF HIS BIRTH. people with "good Saturn" will experince healing, those with low saturn will have negative effects. secondary factors will be the intentions of everybody involved in acquring and using it and the rituals around the situation. size and purity also matter a lot.
